Answer:
x=
3
/2
Step-by-step explanation:
12(5x−4.5)=36
(12)(5x)+(12)(−4.5)=36(Distribute)
60x+−54=36
60x−54=36
Step 2: Add 54 to both sides.
60x−54+54=36+54
60x=90
Step 3: Divide both sides by 60.
60x
60
=
90
/60
x=

1. x + 2y -3 =0.
2. x/2 + y/9 = 1/3.
3. 4x-y+7=0.
4. x + y/2 = -1/2.
5. a. 3x-y-1=0.
b. x - y/3 = 1/3.
